What is Pseudoarthrosis?

Pseudarthrosis refers to a failure of fusion after an index procedure intended to obtain spinal arthrodesis [^4,5,12]. The term suggests the presence of a false joint, although it is commonly used to describe a lack of fusion that occurs after an attempted arthrodesis.

What causes pseudarthrosis?

Causes. Pseudarthrosis occurs when bones fail to fuse with one another after spinal fusion surgery. Factors that reduce the ability of bone-producing cells (called osteoblasts) to produce new bone for fusion increase the risk of Pseudarthrosis.

Is pseudarthrosis serious?

Pseudarthrosis or nonunion is the failure of complete spinal fusion and healing. Often, patients report resolution of their symptoms right after their spinal surgery. Unfortunately, several months after their fusion, patients typically experience return of their axial neck or back pain.

What does pseudoarthrosis feel like?

The symptoms of pseudoarthrosis are similar to those of osteoarthritis and include; lack of mobility, persistent pain, joint clicking and in some cases, redness and even fever.

What is pseudoarthrosis of spine?

Pseudarthrosis is the result of failed attempted spinal fusion. This condition typically manifests with axial or radicular pain months to years after the index operation. Diagnosis is based on clinical presentation and imaging studies, after other causes of persistent pain are ruled out.

For patients who have pseudarthrosis, what can they do or try? | Dr. Todd Lanman

How do you fix pseudarthrosis?

Treatment of lumbar pseudarthrosis includes a variety of surgical options such as replacing loose instrumentation, use of more potent biologies, and interbody fusion techniques. Prevention and recognition are important tenets in the algorithm for the management of spinal pseudarthrosis.

How is pseudoarthrosis treated?

Diagnosis of pseudarthrosis involves imaging tests of the spine. The treatment for pseudarthrosis is a second spinal fusion surgery.

Is pseudarthrosis common?

Pseudarthrosis is a common postoperative complication that may occur after anterior or posterior procedures, and can be challenging to diagnose and manage [^8,10,12,53].

Is pseudarthrosis a disability?

Lumbar pseudarthrosis is a potential complication of lumbar arthrodesis and can be associated with significant pain and disability.

Why is Pseudoarthrosis painful?

Pseudarthrosis Causes

One problem with these surgical procedures is that the graft material that they use for the fusion doesn't fully form to create solid bone tissue. If this happens, the impacted area will still have movement, and you can still experience pain.

How is lumbar pseudarthrosis treated?

Treatment of lumbar pseudarthrosis includes a variety of surgical options such as replacing loose instrumentation, use of more potent biologics, and interbody fusion techniques. Prevention and recognition are important tenets in the algorithm for the management of spinal pseudarthrosis.

What is pseudarthrosis L5 s1?

Lumbar pseudarthrosis is defined by a failed union after fusion surgery, leading to the anatomical condition of continued significant motion of the spinal lumbar motion segment. This condition can lead to back pain, radicular pain, deformity, and hardware failure.

What happens if bones don't fuse after spinal fusion?

If the bone doesn't actually knit together, the screws and rods will predictably work themselves loose over time, or even break. Once this happens, patients may develop either new back pain or recurrent leg symptoms. The other big category is that of continued degeneration at a level next to a previous surgery.

Will a non union eventually heal?

A nonunion is a broken bone that has not healed. Most fractures—broken bones—will heal effectively with standard treatment in about 6 to 12 weeks. Between 5 and 10 percent, however, may fail to heal completely.

Why would a bone not heal?

Blood brings oxygen, healing cells and growth factors to the bone to allow it to heal. If a fractured bone is left unstable or lacks blood supply, it can lead to a nonunion. Factors including the use of tobacco or nicotine can impede bone healing and increase the risk of nonunion.

What conditions automatically qualify you for disability?

How many years does a spinal fusion last?

Surgical screws, rods or metal plates are used to hold the vertebrae together. In more complex cases, two or more interlocking vertebrae may be involved in the spinal fusion procedure. The results of a fusion are permanent.

Can spinal fusion cause problems later in life?

The most common thing we see in the clinic in patients who have spinal fusion complications years later is either a return of back pain or new symptoms. These both indicate possible new disease.

What does a failed spinal fusion feel like?

Symptoms may include chronic pain in the back, neck, or legs, which can be dull or sharp, aching, burning, or radiating. The pain may continue after surgery or reappear several days or weeks afterward. It can worsen as scar tissue builds in the spinal nerve roots, which extend from the spinal cord.

What are the signs of a failed cervical fusion?

What is post laminectomy syndrome?

A laminectomy is a surgery that reduces pressure on the nerves in the spinal cord by removing a part of a vertebra. Post laminectomy syndrome is a condition in which the patient continues to feel pain after undergoing a correctional laminectomy or another form of back surgery.

Is myelopathy a neurological disorder?

Causes of myelopathy include spinal stenosis, spinal trauma and spinal infections, as well as autoimmune, oncological, neurological and congenital disorders. Myelopathy can be cervical and thoracic; cervical myelopathy is the most prevalent. Myelopathy is typically a gradual degenerative process affecting older adults.

Is spinal fusion a disability?

There is no specific disability listing for back surgery or spinal fusion, but if the surgery didn't correct your impairments, you might meet the requirements of a listing based on the impairments that led you to need back surgery or spinal fusion.

Are there any permanent restrictions after spinal fusion?

You may find that after you spinal fusion, you run into some restrictions like being unable to lift, bend or twist. Many of these permanent restrictions are not actually permanent. After a 3 to 6 month healing process, you may find that your restrictions lessen and are able to get back to work.

Can you feel the screws after spinal fusion?

Often, excessive pain is a symptom of a loose screw after spinal fusion or other hardware complication. “If the hardware is prominent under the skin the patient may feel a painful bump,” Dr.
